ANTIRATTLING THILL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 606,307, dated June 28, 1898.

Application filed August 3, 1897.

To all whom it may concern:

Be it known that I, WILLIAM E. SHERwooD, of Oneida, in the county of Madison and State of New York, have invented a new and useful Antirattling Thill-Coupling, of which the following is a specification.

My invention relates to certain improvements in antirattling thill-couplings and the main objects of myimprovements are to provide simple, speedy, and convenient means for the removal of the shafts or pole without the use of nuts also, to provide simple, cheap, and efficient means for the prevention of rattling.

Vith these objects in view my invention consists in the novel construction, combination, and arrangement of parts, such as will be herein after fully described, and specifically pointed out in the appended claim.

Referring to the drawings, in which similar letters of reference indicate similar parts, Figure 1 is a perspective view of my thillcoupling, showing the same applied to an axle and shaft. Fig. 2 is a central transverse section taken through the coupling and axle, showing the aXle-clip in side elevation. Fig. 3 is a sectional view taken through the coupling-bolt. Fig. 4 is a detail perspective view of the rubber block or cushion, together with a bearing-plate to be used for preventing the Wear of said block. Fig. 5 is a detail perspective of the shaft-pin. Fig. 6 is a detail perspective of the supporting-frame for the rubber block or cushion. Fig. 7 is a detail perspective of the looking-lever, and Fig. 8 is asimilar view of the connecting-link forming a part of the looking mechanism.

Referring to the drawings by letter, A desi gnates the axle, to which is secured the clip B, provided with the usual shackle or frame B', for the reception of the thill-iron O, all of these being the ordinary and well-known parts. Through the eye of the thill-iron Cis passed the coupling-pin D, provided withl a head D', which is bifurcated at Dgfor the reception of the upwardlyprojecting lug E' of the frame E. This coupling-pin D is provided With a squared portion D3, which is adapted to enter a correspondingly-squared hole provided in one of the ears B' of the clip B and serves to prevent the said coupling-pin serial No. 646,976. (No model.)

and antirattling-block from turning with the thill-iron and shaft. A rivet or screw E2 is provided for hinging these parts together. F indicates the antirattling block or cushion, which is preferably constructed of rubber and is secured, in the frame E by any suitable means, but preferably by a'projecting lip F', which is adapted to be bent into a slot F2, provided in the frontl face of said block F.

The upper surface of the block or cushion F is concave to conform with the periphery of the thill-iron and is provided with a bearingplate G to prevent wear of the said block F, caused by frictional contact. This bearingplate G is secured to the block F by means of projecting lips G', which are bent into slots G2, provided in said block F.

On the left-hand side of the frame E is a lug E3, to which is pivoted at E4 a lockinglever H. To the right of the pivotal point of this lever H is a hole through which passes the lower end of a link I, the top of which passes over and fits into a groove I', provided in the end of the coupling-bolt D.

It Will be readily' seen that when it is desired to uncouple the thill it is only necessary to swing out the eccen'trically-pivoted lever H, which loosens the hold of the link I on the coupling-bolt D and allows it to pass out of the groove I' and oif of said bolt, thereby releasing the frame E and the block F, which will swing down on its hinge Il2 and permit the coupling-bolt to be withdrawn.

By my above-described construction I am enabled to do entirely away with nuts and avoid the necessity of using awrench. When my coupling is locked, the rubber block or cushion F is tightly compressed and bears against the thill iron and shackle, thereby making a perfect antirattling device.

If the rubber block or cushion should wear or lose its elastic'ity by exposure or otherwise, it can be easily removed and replaced.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-l- The combination With the Vaxle-clip and thill-iron, a coupling-pin provided with a squared end adapted to fit in a correspondingly-shaped opening in the clip-car, a projecting bifurcated head for said coupling-pin,
